    Default Ethos 21mm



    Went up north for a few day's. Missed the delivery for my Tele Vue Ethos 21mm. So off to the post office I go. Anyone familiar with Ethos 21mm?

    No, but I'm quite jealous. My mouth is salivating thinking about a new TV Ethos.

    I bought one two years ago but sold it after a few months. Though it is very sharp and does what it was designed to do very well, I found I didn't like the 15mm eye relief coupled with the large eye lens and the super wide view.
    I had trouble seeing the edge of field, and didn't take to the 'peering around the corner' nature of such a wide AFoV, so for me my Nagler 22T4 gave a more comfortable way of seeing the 'same' amount of sky.

    Having said that, I am sure you will love it for the sharpness and high contrast views....and hope you find it comfortable as they are really sharp, my Ethos 13mm gave me some of the best views of M42 in many years....

    I wear glasses. So for me it helps. Hate taking glasses off and on. When viewing.

    I bought the 21 Ethos when it first came out. A first rate EP and you will not be a bit sorry to own it. In my TV NP-101 it is perfect.

    It should give a magic, beautifully sharp view in that scope: so long as you are happy to move your head around to see it all! It will certainly kill your Celestron K25!

    Let's know how it goes.

    All the best,

    Dean

    When it clears up for more then a few minutes. I very rarely use the old K25. It came with the scope back in 1976. That's when the EPs where made in Japan. Quality was good. Not many EP manufacturers choices back then. That I can remember. My memory is excellent, just short.

    Yep, nothing wrong with a well made Kellner. Very sharp, but also very narrow field. This is where the Ethos will excel.
